Twin Quad NOR Flash Memory Model

Overview

Twin Quad NOR Flash Memory Model provides an smart way to verify the Twin Quad NOR Flash component of a SOC or a ASIC. The SmartDV's Twin Quad NOR Flash memory model is fully compliant with standard Twin Quad NOR Flash Specification and provides the following features. Better than Denali Memory Models.

Twin Quad NOR Flash Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

Twin Quad NOR Flash Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
